Overview

The mentioned entity has been in existence since 2011 and was introduced in conjunction with the achievement Valve Gift Grab 2011 - L4D2. Its purpose is to collect three gifts dropped by Special Infected in Versus Mode.

Features

The gifts spawn for killed special infected and tanks, not for common/uncommon infected or the witch. Only players on the survivor team are able to collect the gifts. Both survivors and Special Infected/Tank can be the killer to obtain a gift drop. Even if the Special Infected/Tank is killed by the world (e.g. Any trigger_hurt or drowning), it can still trigger a gift drop.

Factors affecting gift spawning

Several factors determine whether a gift will spawn:

  1. The Convar: z_holiday_gift_drop_chance (default value: 0.3), indicating a 30% chance, with a minimum value of 0 and a maximum value of 1
  2. The date: Gifts spawn between December 1st and January 2nd (inclusive).
  3. Time interval: A new gift will only spawn after approximately 16 seconds have passed since the last one was dropped.

Gift lifespan

When a gift is not collected by any player, it will automatically despawn after 30 seconds.
